i know most dealerships don't care about catbacks as far as voiding the warranty.. especially since they're the ones that install the SPT. that wasn't my concern at all. my only concern is being about to fight tickets.. so that being said, does the 2.5" exhaust compromise performance in the 350-375 whp range? (that's my overall target HP)
